I don’t see any reports of this against Audacity on the Ubuntu bug tracker: https://bugs.launchpad.net/ubuntu/+bugs?field.searchtext=audacity but you can find reports online of error 4 in libc* in various applications and different Linux distributions. It’s usually some kind of conflict between libc and other libraries or other applications.
Have you tried starting Audacity from the terminal to see what messages that produces?
Has the problem only just started now? If so, have you just installed any other new packages? If you close down all applications except Audacity, do you still have the problem?
i also startet audacity in GDB:
(gdb) file /usr/bin/audacity
(gdb) run
Starting program: /usr/bin/audacity

but what do i with this information? i’m no coder/programmer…
GDB again:

Thanks for testing it in gdb. I think the problem is specific to your computer and that you should ask on the Ubuntu forums. They are more likely to be able to help you with library problems, because they supply the libraries and the operating system.
